Single Phase Pad Mounted Transformer

 

Farady Electric’s single phase pad mounted distribution transformers provide a reliable  and affordable solution for clients who need to reduce their overall operating costs. they  are low-profile, compartment-type tranformers,which are generally used for step-down purposes from an undergroud primary cable supply suitable for mounting outdoors on  pads without additional protective enclosures,and meet the following standard:
IEC60076,ANSI/IEEEC57.12.00, C57.12.20,C57.12.38, C57.12.90, BS171, SABS 780 etc

Our single phase and three phase pad-mounted  distribution transformer is commonly used in various places including rural areas, remote regions and scattered villages to provide high quality power supply for daily lighting, agricultural production and industrial plants. Aside from these, it is also suitable for the energy saving projects for railway and urban grid.
